How does Google Adwords Enhanced CPC Work?
Google recently announced an upgrade to the Google Adwords tool for advertisers; Enhanced CPC (http://adwords.blogspot.com/2010/08/increase-roi-conversions-with-enhanced.html) Google is promoting this function as as a way to ‘turbocharge your ROI’.
How does it work?
In campaigns where you have Conversion Tracking enabled (or you’re importing Google Analytics Goals) you can enable Enhanced CPC. It works for both Search and Display and it can also be used if you are utilising third party bid management tools.
Once activated, the system will use historical account data and factors such as users’ time and location to analyse on-the-fly the likelihood of specific search terms converting, raising or lowering your bids accordingly. Initially 50% of traffic will have bids modified, with the other 50% held back as a control. Over time and with success, the control ratio will decrease.
You’ll find the option to switch it on in your Campaign settings. It works with both manual and automatic bidding.
The Caveats?
Firstly, Google Adwords reports do not currently show any reporting data to indicate how Enhanced CPC has directly affected performance, or indeed which bid-upon keywords have had Enhanced CPC applied and when. You can obviously look at top-level conversion volume and CPA but this doesn’t really give you the visibility needed.
Secondly, if you use Adwords Editor frequently for modifications, bear in mind that with Enhanced CPC enabled in any campaign, you will not be able to use Editor to modify anything in that campaign. This is a significant oversight at launch but we believe Google is working on this.
So does it work?
Well, it’s still early days, but having tested it since launch in a selection of campaigns with a long history and a good volume of conversions we have indeed seen more conversions at a lower CPA, after an initial drop in performance.
Overall, we’d say approach with caution and don’t simply assume that the tool will provide that turbocharge without any input from you. Some commentators have called it a charter for the lazy manager but we say why ignore something that can improve your ROI?
If you want to test it then give it time to settle in. Don’t see it as a reason to not to continue keeping a close eye on optimisation. And before you switch it on, if your CPA is at the top-end of your target range, you may want to adjust some bids downward, given that Google will bid up to 30% higher than your current bid.
